Abstract

The laser beam quality measurement has become a hot topic in the field of laser engineering nowadays. Based on the method of Hartmann-Shack, the four-wave lateral shearing interferometer is presented in this paper to achieve the laser beam shape parameters. The principle of shearing technology is described in detail. Parameters of semiconductor laser at 532nm and ZYGO interferometer laser are tested based on the method of four-wave lateral shearing interference and their test results are compared with the nominal parameters. As the results, the test results are basically consistent with the nominal value, which fully shows the feasibility of the four-wave lateral shearing interference method.
